BICYCLE-PEDAL.

SPECIFICATION forming part of Letters Patent No. 584,453, dated June 15, 1897.

Application filed November 15, 1895. Serial No. 569,027. (No model.)

To all whom, it may concern:

Be it known that we, FRANK H. BOLTE, THOMAS A. DONLEVY, and JAMES R. CON- NELL, citizens of the United States, and residents of Milwaukee, in the county of Milwaukee and State of \Visconsin, have invented certain new and useful Improvements in Bicycle-Pedals; and we do hereby declare that the following is a full, clear, and exact description thereof.

Our invention has for its objectto provide a simple, economical, and strong bicycle-pedal of the rat-trap variety; and it consists in certain peculiarities of construction and combination of parts hereinafterset forthwith reference t0 the accompanying drawings and subsequently claimed.

In the drawings, Figure 1 represents a partly-sectional view of a bicycle-pedal constructed according to our invention as it ap pears partly in longitudinal section; Fig. 2, a transverse section of the same; Fig. 3, a detail elevation of an adjustable ball-cup; Fig. at, an elevation of the foot-plate before the same is bent, and Fig. 5 a vertical transverse section taken through the center of said plate.

Referring byletter to the drawings, A represents a barrel that is hollow for the greater portion of its length and enlarged at its inner end to form a housing b, the latter being tapped upon its interior for the engagement of a screw-threaded ball-race B, having a serrated inner edge.

Seated in the barrel A against solid metal at the outer terminus of the bore is a balloup C, and engaging this cup, against the balls 0 therein, is the cone-shaped outer end of a pin D, the other end of this pin being shouldered and in cone-bearing against balls d within the confines of the race B, the latter being held in adjusted position by the engagement of its serrated edge with a set-screw E, arranged to turn in housing portion b of said barrel. The adjustment of the ball-race B regulates the bearings for the pin, and the latter may be attached to a crank-arm in any suitable manner the one herein shown being of the variety organized for screw connection with an outturned end of such a crank.

Extendinglaterally from the exterior of the barrel A in opposite directions are tapped bosses e, and a suitably-bent fo0tplate F is connected to these bosses and the tapped but otherwise'solid outer end of said barrel by means of screwsf, this being a very secure, simple, and effective manner of maintaining said foot-plate in position.

The foot-plate is made from a single piece of metal serrated on its edges and shaped to present foot-guards g at its ends, as well as similar guards h at its center. I11 order to stiffen the plate F, the latter is swaged to present a rib i, that extends from end to end of said plate.

By having the plate F rigidly connected to the outer end-of the barrel A the pedal is materially strengthened and less liable to injury if brought into forcible contact with a road way or other surface.

While certain features of the pedal may be varied in the matters of detail, we attach particular importance to the pin-barrel having the three connecting-points for'the one-piece foot-plate that is bent to present parallel ser- 5 rated edges in the direction of said barrel. Particular importance is also attached to the ball-cup C, set in the barrel A against the solid metal at the outer terminus of the bore of said barrel, it being an easy and comparatively inexpensive matter to properly temper said cup for ball contact and to replace a cup that may be defective. To properly temper the barrel itself for contact with the balls 0 in the absence of cup C is a difiicult and expensive matter, and in case of defect or wear a new barrel would be necessary.

Having now fully described ourinvention, what we claim as new, and desire to secure by Letters Patent, is

1. A bicycle-pedal comprisinga pin-barrel hollow for the greater portion of its length and provided with bosses extending laterally therefrom in opposite directions, and a continuous foot-plate made fast to the bosses and solid end portion of the barrel.

2. A bicycle-pedal comprising a pin-barrel that is hollow for the greater portion of its length in an outward direction andhas its in-' ner end enlarged to form a housing, a ball-cup seated in the barrel against the solid metal end of same, a ball-race having serew'-thread adjustment in the housing and provided with serrations on its inner edge, a set-screw adjustable in the housing longitudinally of said barrel to engage the serrated edge of the ballrace, bosses extendinglaterally from the barrel in opposite directions therefrom, and a continuous foot-plate made fast to the bosses and outer abutting end of the aforesaid barrel.

3. A bicycle-pedal comprising apin attachable to a crank-arm, a partly hollow barrel in ball-bearing on the pin having a tapped but otherwise solid outer end, tapped bosses extended laterally in opposite directions from the pinbarrel intermediate of its extremities," and a foot-plate connected by screws to the V bosses and outer tapped end of said barrel.

In testimony that we claim the foregoing we have hereunto set our hands, at Milwaukee,

in the county of Milwaukee and State of Wiscousin, in the presence of two Witnesses.
